TANK- -CAB-CLEANING DEVICE.

Application filed Kay 2,

This invention relates to a cleaning device for tank cars andother tanks.

The object of the invention is to .provide a device for cleaning tank cars or other tanks which have no opening except at the top so as to avoid the necessit of removing the tank and turning it upsi e down when it is desired to Wash out the tank. 7

Another object is to so construct a device 10 of this character that the cleansing fluid may reach all parts of the tank.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the recise' embodiment of the invention herein isclosed may be made within the scope of what is claimed without departing from the spirit of the invention..

In the accompanying drawings Figure 1 represents a side elevation of a:

tank with parts broken out and in section,

.25 the device constitutingthis invention being shown applied and in side elevation, and

Fig.2 is a top plan view thereof.

In the embodiment illustrated a tank T is shown' having a filling chamber C located on the top thereof and closed air tight. in the usual manner, an air inlet pipe I being shown entering said chamber while a discharge pipe or outlet 0 extends through the chamber to a point near the bottom of the found in tank cars andof the invention.

The attachment constituting this invenconstitute no part tion comprises a removable closure 1 for the and to prevent air entering around it. This pipe 2 extends to a point near the bottom of 4 tank T and is equipped with a luralit of series of spaced discharge nozz es 3 w ich extend laterally from the pipe and on' therotation of said pipe discharges the cleansing fluid in all directions so as to reach re- 5o mote portions of the tank and thereby thor I oughly agitate the contents thereof and eflitank. All of these parts are those ordinarily 192a. Serial no. 558,015.

or less is admitted through pipe 2 and s'ufiiv cient air inlet to orce water in the tank up through the discharge pipe as fast as it is admitted ressure is inserted through the through pipe 2. The water under pressure passing out through the nozzles 3 will be sprayed inall directions and the turning of the pipe 2 will bring it into contact with all walls of the tank keeping the contents thoroughly agitated so that all sediment in the tank will be carried outthrough the discharge pipe 0 and discharged at any suitable point. r

The pipe 2 is shown held enga ed with the closure 1 and is suitably secure in any desired manner tothe pipe and to said closure.

From the above description it will be seen that when it is desired to clean a tank T all that is necessary is to insert the pipe 2 in the manner above set forth, supply water under pressure thereto, and air under pressure to pipe I and the tank will thoroughly be cleaned without necessitating the removal thereof from its support and t e turning of it upside down as is now necessary with tanks of this character.

I claim In a device of the character described, a removable closure adapted to be fitted into the opening of atank, a water suppl pipe extending throu h the removable c osure, means for provi mg a fluid-ti ht connection between the pipe and closure, orizontal dischargenozzles at the lower end of the pi e, said pipe adapted'to extend to a(point ad acent to the bottom of the tank, an upwar 1y inclined nozzles communicating with the pipe .and arranged at a point in spaced relation with the lower end of the pipe, and means for rotating the pipe to direct jets of water to every point of the interior of the tank.

my own, I have hereto aflixed my signature.

In testimony that I claim the foregoing as
